While lower vertebrates can repair their adult hearts after a heart attack, mammals -- including humans -- cannot. The ability to regenerate dead muscle tissue in mammalian hearts disappears just a few days after birth because the heart muscle cells, called cardiomyocytes, exit the cell cycle. In 2020, researchers reported that surgery to remove the left ventricle apex of the heart of pigs, one day after birth, somehow extended the replication ability of heart muscle cells. To better understand the underlying gene expression changes in this extended regeneration window, researchers now report nuclear RNA-sequencing of heart muscle cells, using this porcine model. From such knowledge, and much further research yet to come, clinicians may potentially learn how to regenerate adult heart cardiomyocytes after a heart attack.

Along with high blood pressure, diabetes, and smoking, environmental factors such as air pollution are highly predictive of people's chances of dying, especially from heart attack and stroke, a new study shows.

In the largest epidemiologic study of arsenic and birth outcomes to date, researchers estimated arsenic levels in U.S. private well water sources by county and compared estimates to documented birth outcomes. They found an association between estimated groundwater arsenic concentration and risk of low birth weight.

Automation in disease diagnosis is reliant on deep learning models that can accurately and efficiently identify measurements of tumors, tissue volume, or other sorts of abnormalities. Now, researchers have unveiled a new, resource-light model capable of identifying many common eye diseases.

The neural and cognitive complexity of the octopus could originate from a molecular analogy with the human brain, according to a new study. The research shows that the same 'jumping genes' are active both in the human brain and in the brain of two species, Octopus vulgaris, the common octopus, and Octopus bimaculoides, the Californian octopus.

The female hormone estradiol was found to suppress psoriasis in mice by regulating neutrophil and macrophage cells. The conditional knockout mice without the natural ovarian hormones estradiol showed symptoms of severe skin inflammation.

Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical analysis. It works using a technique called Raman spectroscopy, where laser light aimed at the sensor is changed slightly depending on whatever chemicals are present on the skin at that point. The sensor can be finely tuned to be extremely sensitive, and is robust enough for practical use.
